Photos taken in Las Vegas from August 5th to 11th at Black Hat USA 2019 and DEF CON 27. I did not take quite as many photos as in previous years, since schedules didn’t align well for portrait sessions, but I’m happy with the environmental shots that I did manage to capture! Technical: Sony A7R II with a single lens, the Voigtlander Nokton Classic 35mm 1.4. While this is a currently-manufactured lens by Voigtlander for the Sony FE mount, with electronic contacts for EXIF data, it is a manual focus lens with an older optical design, providing a more “classic” rendering than modern lenses. I think of it as the newest “vintage” lens I shoot with.
